RizonSDI ® Automatic On-line SDI Monitor    
 


 
RizonSDI® Automatic On-line SDI Monitor,
an online control system, is specially designed
for continuous and automatic desalination
process and other water treatment. Used for
critical water quality monitoring, it achieves
precise control by safe and economical
operations. It replaces the manual,
error prone, conventional procedure
with an automatic,
precise and infallible routine  
  
Application

 RO system on-line testing
 Sea Water Desalination
 Common Water Treatment
 Large scale plants that unattended operation
